java - JOption call method from String text? -

i'm not sure how ask question here is. please @ code (which abbreviated convenience, , don't worry "sam" temporary)

public class jeopardygui_main11 extends javax.swing.jframe {  /**  * creates new form jeopardygui_main  */  public jeopardygui_main11() {     initcomponents();     setdefaultcloseoperation( jframe.exit_on_close );

at "area in question" put location of problem. optiondialog box needs string text, want replace string "public void info()" randomized math.random.

so, optiondialog should read "sam" (in middle text area) if run properly.

i'm sorry if did not make clear enough, ask anything, i'll waiting response, thanks!

here basic example of different way structure program may more efficient:

public class { public static void main(string[] args) throws classnotfoundexception{     getinfo();//set random question , answer      object[] options = {"yes, please", "no way!"};     int n = joptionpane.showoptiondialog(null,             so.question,//reference question set             "",             joptionpane.yes_no_option,             joptionpane.plain_message,             null,     //do not use custom icon             options,  //the titles of buttons             options[0]); //default button title      joptionpane.showmessagedialog(null, so.answer); }  public static void getinfo(){ //will set question , answer     int category = new random().nextint(2 - 0);//random number category     int choice = new random().nextint(2 - 0);//random selection      so.question = questions[category][choice];//get question     so.answer = answers[category][choice];//answer located in same position in answers array }  /*each category represented seperate array within questions  * 2 dimensional array.  these declared static fields or 'global fields'  * way accessible , initialised once  */ private static string[][] questions = new string[][]{      {"question 1, category 1", "question 2 category 1"},//questions[0][*] 1 category      {"question 1 category 2", "question 2 category 2"}//questions[1][*] on category };  /*the answers array mirrors other array each answer in 2d array   * in same position relevant question in questions array  *   */ private static string[][] answers = new string[][]{      {"answer 1 category 1", "answer 2 category 1"}, //answers[0][*] questions [0][*]       {"answer 1 category 2", "answer 2 category 2"}//answers[1][*] questions [1][*] };  //these each hold question , answer private static string question; private static string answer; 

}

i have made lot smaller can feel how it's working. 'global variable' have been suggested @ bottom. should allow question , answer require joptionpane , prevent continual re-initialisation of arrays.

once again, if unsure comment me , i'll see can do. luck!
